TO
TG
TO: Time-out Value
When a value is written to this register, a Start Time-out command is automatically performed.
Time-out duration = TO x 4 x Bit period
TG: Time-guard Value
Time-guard duration = TG x Bit period

Disables the RX Time-out function.
The Time-out counter is loaded with TO when the Start Time-out command is given or
when each new data character is received (after reception has started).
Disables the TX Time-guard function.
TXD is inactive high after the transmission of each character for the time-guard
duration.
